Abstract
A method of ionisation is disclosed in which a sample is heated such that analyte is released from the sample. Analyte released from the sample is accumulated, and then the accumulated analyte is passed to an ionisation region where the analyte is ionised.
Claims18
A method of ionisation comprising:
- heating a sample such that analyte is released from the sample in one or more heating and/or accumulation regions, wherein a first inlet valve and a first outlet valve are operated in a closed state while accumulating the analyte;
- accumulating analyte released from the sample;
- and then
- passing the accumulated analyte to an ionisation region by opening the first inlet valve and the first outlet valve, and ionising the analyte.

A method of ionisation comprising:
- passing gas from a test volume into one or more heating and/or accumulation regions, where the one or more heating and/or accumulation regions comprise an adsorbate or adsorber;
- heating the adsorbate or adsorber such that analyte is released from the adsorbate or adsorber;
- accumulating analyte released from the adsorbate or adsorber, wherein a first inlet valve and a first outlet valve are operated in a closed state while accumulating the analyte;
- and then
- passing the accumulated analyte to an ionisation region by opening the first inlet valve and the first outlet valve, and ionising the analyte.
2 more elements
An ion source comprising:
- a heater configured to heat a sample such that analyte is released from the sample;
- one or more accumulation regions arranged to accumulate analyte released from the sample;
- a first inlet valve and a first outlet valve;
- and
- an ionisation region comprising an ionisation device configured to ionise the analyte;
- wherein the ion source is operable to heat the sample using the heater and accumulate the analyte released from the sample in said one or more accumulation regions whilst the first inlet valve and first outlet valve are in a closed state, and then pass the accumulated analyte to the ionisation region by opening the first inlet valve and the first outlet valve.
